    I recently had some DNS issues so in an event to rectify the problem I uninstalled DNS from all my DNS servers and then reinstalled DNS again.

    I have a single 2003 domain with 3 primary DNS servers that are also DC’s. Replication between them seems to be fine. However an intermittent problem occurrs where a name is not resolved.

    When i open DNS and look at the Forward Lookup Zone i see the following:

    yourdomain.com
    —>_msdcs
    —>_sites
    —>_tcp
    —>_udp
    —>…

    The forward lookup zone is identical on all 3 DNS servers. There is no _msdcs.yourdomain.com above yourdomain.com

    The _msdcs below yourdomain.com is not a delegation (not greyed).

    How do I go about getting the _msdcs.yourdomain.com zone back??

    Should the forward lookup zone look like this:

    _msdcs.yourdomain.com
    yourdomain.com
    —>_msdcs
    —>_sites
    —>_tcp
    —>_udp
    —>…

    I don’t quite understand this whole _msdcs thing.
